Permissions fix on mysql data directory to avoid errors during `vagrant up`
Ignore entire wp-content directory in wordpress-default
Added support for configuring MySQL through the my.cnf file. Any changes made while vagrant is up should be properly detected via Watchr and recopied over to the MySQL dir & restarted. There was some weird issues with trying to symlink this my.cnf file so cp worked just fine. Also added a init.sql script that will create a user for external purposes like Sequel Pro and PHPStorm 6 without SSH - more details on this soon. The actual MySQL query could probably be perfected so it doesn't cause an error when the user already exists ( on 1+n boots )
Ignore data directories created by mysql
Merge remote-tracking branch 'carldanley/master' into vvvv-0.2
Specify database name during database import

Mysql needs a database name to be specified if it isn't already so in the SQL file being imported
Refactor handling of initial database setup

Our naming convention was a little weird before and various scripts for mysql were kind of hidden all over. This does a few things...

* Establishes an init.sql file that creates our default WordPress database and an external user to be used by the local machine for non SSH tunnel connections to mysql. This init.sql file will be where any SQL specific to this vagrant repo will be stored.

* Establishes the concept of an init-custom.sql file that will be used on individual setups to control the databases and users created during a vagrant up. This file must be created by the user, but a sample is included in init-custom.sql.sample

* Ditches create-dbs.sql.sample and default-dbs.sql in favor of this new naming convention
* Alters .gitignore in favor of the new naming convention
* Reorgs the order of things in provision.sh to account for the new naming convention
